SPECIFICATION forming part of Letters Patent No. 640,286, dated January2, 1900.

Application filed December 7, 1898. Serial No. 698,535. (No model.)

To (ZZZ whom it may concern.-

Beit known that l, WVILLY HOMANN, manufacturer, a subject of the King ofPrussia, German Emperor, residing at No. 14 Adersstrasse, Dusseldorf,Germany, have invented new and useful Improvements in Bung-Hole Fittingsfor Casks or Barrels, of which the following is a specification.

The present invention relates to improvements in bung-hole fittings forcasks or barrels which, obviating the usual cork plug, consist almostentirely of metal and can easily and effectively be cleaned andconveniently handled. It provides an inexpensive but efiicient devicecapable of ready removal when ever desired.

The invention more particularly refers to certain improvements in theconstruction of bun g-hole fittings, as willbe more fully set outhereinafter, and the essential elements of which are recited in theappended claims.

The invention consists of a fitting to be inserted in the bunghole, theopening being closed by a valve inside the cask. On screwing in the tapsufficiently the valve will open, as hereinafter described.

By way of example the accompanying drawings illustrate various ways ofcarrying out the invention.

Figure l is a front elevation of the bung; Fig. 2, a sectional view ofsame, the screwed end of a tap being shown inserted in the bung. Figs. 3and -l are rear elevations of the bung closed and opened, respectively.Fig. l shows a front elevation of the plug inserted in the bushing. Fig.L is a side elevation of the plug as seen from the right-hand side of Inthe bung-hole of the cask or barrel a bushing a, preferably of metal, isfirmly secured by means of screw-threads and a special screw Z). Thebushing a possesses an eccentric bore 0, the inner portion of which isprovided with a screw-thread, into which is screwed from inside the caska plug e, fitted with a square hole (Z. The inner end of this plug isprovided with a flange-like projection and rests tightly against theedge around the bore a. The inner and narrower end of the hole (Z isconstructed so as to form a valve-seating. A cone or semicircular shapedvalve f fits on this seating. The valve f is fast to an arm h,

rotatably mounted on a pin 9. A spiral spring 15 surrounds the pin 9. Itbears against a flange fast to the inner end of the pin 9 and the arm71. This spiral spring has one ex tremity secured in the pin g, theother extremity being secured to the arm h. The spiral spring is soarranged that it not only constantly tends to press the valve f againstits seating, but also, by being tensioned in View of torsion, to pressthe arm constantly against a stud 7; on the inner face of the bushing a.The plug 6 is provided on its inner face with a proj eotion Z, forming athree-quarter circle. This projection Z assumes the shape of a hook,extending from Z to Z of Figs. 3, i, 4, and 4 with preferably aninclined surface to press the valve f on the arm 71., over which latterthe hook may pass down on its seating. The other end of the projectiongraduallyinclines toward the face of the plug a, this incline em tendingfrom Z to Z of Figs. 3, 1, 4:, and 43. A packing m, of suitablematerial, is placed at the bottom of the wider part of the bore 0.

The tap for emptying the cask is for the purposes of this inventionfitted with an internal screw-thread in its end a to correspond with thescrew-thread on the plug 6 instead of possessing the usual conicalscrew-threaded end.

The invention operates as follows: Supposing the cask to be filled andthe various organs of my improved bung-hole fitting to be in theposition indicated in Figs. 2 and 3, in which position the valve f islocked on its seating by the hook of the projection Z gripping over thearm h, it will be necessary for opening the bung to screw the tap, whichmay be in connection with a pipe to tap at a distance from the cask,onto the plug 6. The internal screw-thread of the tap or cook does notpermit it to be screwed onto the plug 6 so as to reach thepacking-ringm, (see Fig. 2;) but on further screwing the tap the plug cwill be turned with it for about three-quarters of a revolution,whereupon the tap will press against the packing-ring m thus insuringthe tight connection. During the turning of the plug a the hook-shapedpart of the projection Z releases the arm h, the projection being inconnection with the plug e, and consequently turned with it, and theinclined part of the projection Zpasses underneath the arm it, graduallylifting it until the valve f is 01f its seating, whereupon the arm h isturned aside by the incline of the projection, the resistance of thespiral springt' not being sufficient to prevent it, until it bearsagainst a second stud 70 on the inner face of the bushing a. (See Figs.3 and 4.) The hole (1 will now be completely uncovered. In unscrewingthe tap the plug 6 will partake of the tu rning until it has returned toits original position. The arm h, with valve f, will be returned to itsformer position by the tension of the spiral spring-t, which alsopresses the valve f on its seating in addition to the inclined hook ofthe projection Z, which finally locks the arm h with valve f, as inturning the plug 6 this book will grip over the arm h.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a bung-hole fitting having the exitopening uncovered by thecooperation of an internally-screw-threaded tap, a hollow plug insertedin the bung-hole, and an internal valve mounted on a spring-influencedswinging arm, substantially as set forth.

2. In a bung-hole fitting having the exitopening uncovered by thecooperation of the tap, bung-hole plug and internal valve; a bushingprovided with an eccentric bore for the reception of the hollow plug atthe inner end and for the internally-screw-threaded part of the tap atthe outer end, said tap fitting onto the outer end of the hollow plugand a pin secured to the inner face of the bushing, said pin carrying aspring-influenced arm with valve for covering the bore in the plug,substantially as set forth.

3. In a bung-hole fitting having the exitopening uncovered by thecooperation of the tap, bun g-hole plug and internal valve, a hol- 10Wplug screwed into the inner narrower end of the eccentric bore in thebushing, said plug receiving the internally-screw-threaded tap andadapted to be turned thereby, a flange at the inner end of the plugprojecting beyond the eccentric bore in the bushing, a valveseat formedat the inner end of the bore in the plug, said valve-seat adapted toreceive a valve mounted on a spring-influenced swinging arm, and acircular projection on the inner face of the plug around the valve-seat,said projection assuming the shape of a hook, adapted to grip over theswinging arm of the valve, at one end, and the shape of an incline,adapted to lift the valve off its seating by pressing under the swingingarm of the valve when the plug is turned, at the other end,substantially as set forth.

4. In a bung-hole fitting having the exitopening uncovered by thecooperation of the tap, bung-hole plug and internal valve, a pin firmlysecured to the inner face of the bush ing, said pin movably carrying aswinging arm to which the valve for closing the exitopening is secured,and a tensioned and torsioned spiral spring coiled around said pin andsituate between the swinging arm and a flange at the end of the pin,said spiral spring having one extremity secured to the pin, the otherpressing against the swinging arm so as to rest against a stud on thebushing and to insure a tight fitting of the valve on its seating,substantially as set forth.

5. A bung-hole fitting having the exitopening uncovered by thecooperation of the tap, bung-hole plug and internal valve, comprising'in combination a bushing provided with an eccentric bore, avalve-seating in connection with the internal end of the bore in theplug, a hook-shaped and inclined circular projection around thevalve-seating on the inner face of the plug, a valve for closing theexit-opening, a swinging'arm under the influence of the tension andtorsion of a spiral spring carrying the valve, a pin with spiral springcarrying the swinging arm firmly se cured to the inner face of thebushing, and an internally-screw-threaded tap adapted to fit and turnthe outer end of the plug thereby causing the cooperation of the variousparts, substantially as and for the purpose set forth. 7

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
